Abstract
The invention relates to a device for forming laser pulses comprising: an input for a pulsed laser beam; a spatial phase modulator (), arranged on the trajectory of said pulsed laser beam so as to be illuminated thereby; a control means designed to configure said spatial phase modulator so as to emulate a diffraction grating (') having a diffraction efficiency that varies along one spatial direction (s) identified by the intersection of the modulator surface with the diffraction plane (xz); and spatial filtering means () for a light beam diffracted by said grating; whereby a laser pulse (P) at the device input is converted to a train of elementary output pulses (PS) having temporal intensity and/or phase and/or polarization modulation. The invention further relates to a laser pulse forming process based on the use of such a device.
